The caster mechanisms above referred to, each comprise caster wheels 12, the carrying frame 13 of which is arranged below the lower end of the aforesaid shaft 8 and is adapted to receive a transverse movement from said shaft through an operative connection hereinafter described, and such transverse movement of the frame 13 is converted into a vertical movement thereof by links 14 or other equivalent means, interposed between the upper face of the frame 13 and the opposed face of the open bottom recess in the floor plate or base 3 in which an individual caster mechanism is arranged as illustrated in Figs. 5 and 6.

15 designates a crank arm iXedly connected to the lower end of the aforesaid vertical shaft 8 and having a crank pin 15 adapted for operative engagement in alongidinal slot 13 in the mid-portion of the frame 13, so as to impart the above mentioned simultaneous transverse and vertical movements to said frame on a partial rotation of the shaft 8, to move the caster wheels from a normal inactive position into an active position and vice versa. n

16 designates -a shaft extending between and journalled in the casings 5, aforesaid, and carrying gear wheels 17 which gear with the gear wheels 7 of the sleeves 6 to vimpart simultaneous rotation to the same.

18 designates a companion shaft `eXtend ing between and journalled in the aforesaid casings 5, and carrying gear wheels 19 which gear with the gear wheels 11 of the central shafts 8 to impart simultaneous rotation thereto.

The pairs of gear wheels 7. 17 and 11, 19, above described, are preferably of the ordinary spiral type shown, but may be of the ordinary bevel type if so desired.

20 designates agear wheel fixed on one end of the shaft 16, and arranged'within a easing 5, while 21 designates a similar gear wheel fixed on the end ofthe companion shaft 18 and arranged in a longitudinal plane a distance removed from the gear wheel 20.*as shown in Fig. 2, and for the purpose hereinafter set forth.

22 designates an idler gear wheel having operative engagement with the gear wheel 21 and adapted in turn for operative enlgagement with the change gear wheel now to be described.

23 designates a longitudinally shiftable sleeve revolubly mounted in a bearing oritice' in thel casing 5 in which it slides. The sleeve 23 is also supported on a tubular housing 24 and has key and keyway connection therewith so that the two partswill turn in.

unison while permitting the sleeve 23 to have the described sliding movement.

25 designates a head or handle on the exterior of the sleeve 23 for effecting a convenient manual shifting of said sleeve.

26 `designates a change gear wheel secured to one end of the sleeve 23, and adapted in accordance with the position to which said sleeve is shifted, to engage one or the other of the gear wheels 20, 22, above described.

27 designates a non-circular shaft fitting the correspondingly formed bore of the aforesaid supporting housing 24. Said shaft 27 is of greater length than said supporting housing 24 so as to be capable of longitudinal movement inisaid housing and is provided with an operating' hand crank 28 at* one end and with a stop collar 29 'at the other end, to limit its lindependent adjustnient in either direction." i Y VVith'tbe described construction the shaft 27 in its inactive condition is wholly'withinl i the hollow of the horse body l and is enclosed and protected from accidental contact as illustrated in Fig. 1. When required for active use the shaft 27 is pulled out longitudinally through'the passage 4 of the?" horse body in order that said hand crank 28 will be clear of the end of said horse body for convenient manual operation. When the present improvements are applied to avaulting buck or like exercising apparatus in which a single supporting column is only used, the parts will be modified accordingly by the omission of the mechanisms and mechanisms of the secondary' column 2 above described..
